Question about mean-average

Hi all. I am new to statistics and qualtrics and I would like some help understand why I am getting an average of 18.52 in one my questions, whereas all the rest questions (26 in total) show averages of 4.21,3.96,3.50 etc. I have the same number of responses for all questions that is 25 so far.

Can someone help me understand how qualitrics calcuate the average? Is there an error from my side or the platform?

Also, is there a detailed video showing how to automatically calculate a T test in qualtrics? 

Thanks

It’s hard for me to tell without knowing what exact steps you took after the data collection, but considering you only have 25 responses, you could manually edit your data from the “Data & Analysis” tab for the existing responses and ensure that the recode value settings are correct for the upcoming data collection.

Hi,

Can you describe the type of question you used to collect the data, or share a screen shot of it?

Did you apply any validation to the question to prevent outliers from being passed through?

Thank you for your answer. It is a matrix question based on likert scale, strongly disagree - strognly agree. I did not apply any validation. All the other questions display averages around 4. Can you propose how to fix this? or what validation is needed as you describe?

Thank you

Hi @nikipana 

Is it possible your code values for that question are wrong?

Yes, the strognly agree value was missing, and I had to correct it after people submitted their response. Can I fix this now? I guess that participants that wanted to select strongly agree, at the end selected agree, so this is ok for my results. 

How to calculate manually, with the responses I have?

Thanks
